\VILTON F. JENKINS, OF RICHMOND, VIRGINIA TROLLEY- HOLDER.

SPECIFICATION forming part of Letters Patent No. 416,920, dated December10, 1889.

Application filed January 28, 1889- Serial No. 297,798. (No model.)

To all whom it may concern:

Be it knownthat I, WILTON F. JENKINS, a citizen of the United States,and a resident of Richmond, in the county of Henrico and State ofVirginia, have invented certain new and useful Improvements in'lrolley-Holders; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the artto which it appertains to make and use the same,reference being had to the accompanying drawi-ngs, and to letters ofreference marked thereon, which form a part of this specification. 7

Figure l of the drawings is a representation of a side view of thetrolley-holder. Figf 2 is a front view of the same.

This invention has relation to holders or standards for trolleys, beingespecially designed to afford accommodating support to trolleys used inconnection with tramway-cars to engage the electrical cables above saidcars, all as hereinafter set forth.

The object of the invention is to provide a support which, Whilesufficiently firm to insure engagement with the cable, is neverthelessof yielding character and designed to give'readily either in the lateraldirection or in the direction of the length of the cable, so as to avoidinj ury of the trolley or holder or casual disengagement from the cable.

In the accompanying drawings, the letter A designates the main staff orstem, which is securely fastened to the top of the car, being usuallybraced by means of guys B or other common bracing devices.

O is a laterally-swinging frame, which is pivoted to the upper end ofthe stem A by the pivot D. This frame extends upward and downward fromthe pivotal point, and its upward extension E has arms F, which aredesigned to support the trolley-hanger G, which frame C in eitherdirection.

- is transversely pivoted to such extension at the point H, so as toswing forward or backward, according to the direction in which the caris running. The lower extension K of the frame 0 is provided with aslot-guide L, which plays on the lower part of the stem A and allows asmall lateral movement of the The trolley-hanger G extends above an(below the pivot II, and carries pivoted to its arms the trolley N, whichis held upward by weighting the lower end of the hanger, as at IV, sothat a sufficient tension is provided to 5 5 insure engagement with thecable.

It will be apparent that the trolley pivoted. to the hanger G can movereadily either forward or backward or laterally to accommodate itself tothe position of the cable, which may not be precisely central. So, also,the hanger can readily yield to the swing of the cable between itsbearings, and it readily accommodates itself to the lateral motions ofthe car caused by uneven track, inequality of loading, or to anyswerving in passing around curves. The hanger, it will be observed,adjusts itself automatically when the direction of motion of the car ischanged.

Having described this invention, what I
